GPS Units in Trucks

I have a Garmin 750. It's awesome! The thing with a regular GPS is you just have to realize and know it's only gonna be 90-95% reliable. I still call ahead for directions, parking info, and do proper trip planning with Atlas and QC directions. For low bridges and truck restricted routes you need to pay attention/drive as these are all clearly marked with signs. My GPS will recalculate automatically if I stay on a truck route when it requested I turn. You'll learn when to ignore the GPS and just drive where you must.

I'll call the consignee right away sometimes or wait until the day before I deliver it just depends on the circumstances and their hours of operation.

 

I have a Garmin 780 in the truck, 90% of the time it's right. Since I know where 90% of my customers are anyhow, I use it more to give my dispatcher a rough time on when I'll arrive.

 

I am sold on GPS(Garmin), it's an aid and the final authority but it has increased my driving productivity by a large degree. I have a handheld gps which shows weigh stations and exits on the interstates also. It won't route me but it darned sure assists me in getting a heads up or finallizing my log entries when I need nearest town.

 

Is the pricey trucker version of the Gramins (465t) worht the price? I would rather hold off initially buying a gps unit and use the old trusty atlas. I would rather save the money and buy the higher end gps in the long run. Or is it better to buy an affordable unit at local wally world?

I'm pretty sure I will buy the cheapo garmin, then upgrade down the line.
Thanx for the feedback.
